It has been shown that IAQ has an impact on the comfort, health and well-being of the building inhabitants. Indoor air quality (IAQ) is refers to the air quality inside and around structures and buildings. It is measured by collecting samples from building surfaces and air, monitoring the exposure to contaminants, and evaluating airflow within the buildings through computer modeling. IAQ issues are mostly caused due to the indoor pollution sources that discharge particles or gases into the air.
